Die Analyse war spannend, hat mir echt die Augen geöffnet.

Ein bisschen aufwändig, aber super hilfreich bei meinen Erschöpfungssymptomen.

Der Test war einfach, aber die Ergebnisse sehr aufschlussreich. Jetzt weiß ich, warum ich so müde war.

Der Test war sehr aufschlussreich! Ich konnte endlich besser verstehen, wie mein Tryptophan-Stoffwechsel funktioniert und welchen Einfluss er auf Serotonin, Stimmung und Schlaf hat. war verständlich und hilfreich – ideal für alle, die Ursachenforschung in der funktionellen Medizin betreiben möchten. Sehr empfehlenswert!

Principle

Measure first, then decide

Without measured values, any treatment is guesswork. We turn the order around: first the lab report, then the decision.

Consultation to put the measured values in context

01
Measure Kynurenine axis, serotonin and catecholamines from one urine sample, analysed at the partner laboratory in Germany.
Neurotransmitter tryptophan metabolism plus · urine · 7–21 days from sample arrival
02
See where you stand Every value appears in the lab report with the laboratory's reference range. You can see which values fall inside it and which do not.
Lab report including a consultation
03
Targeted, not generic Instead of a standard package you take what your values point to — agreed with a practitioner.
Initial consultation, 10 minutes, free
04
Measure again after a few months The same analysis a second time shows how the values have changed.
Earliest sensible interval: 3 months

Ory experts are there for you

Doctors and non-medical practitioners from the Ory team are with you all the way — for the lab report and everything after.

Initial consultation

What a value means, and whether a supplement is right for you, is something to discuss with a practitioner. This page makes no recommendation and is no substitute for medical assessment.

Details

What this analysis covers

What is measured

The full kynurenine axis, serotonin and catecholamines by LC-MS from one urine sample.

F620 Kynurenine axis IDO/KMO activity indices, quinolinic acid, kynurenic acid

F620 Serotonin & tryptophan Precursor and end product of serotonin metabolism

F620 Catecholamines Dopamine, adrenaline, noradrenaline for the full neurochemical balance

The biomarker reference explains what lies behind the numbers: how values interact, which cofactors are involved and which biochemical processes take place in the body — for all values and areas, not only this analysis.

To the biomarker reference

For whom

The test suits exhaustion, brain fog, sleep problems or stress intolerance, where a particularly precise, LC-MS-based picture of tryptophan metabolism beyond the standard panels is wanted.

What a single value means in your situation is something to discuss with a practitioner. It does not replace medical assessment.

How it works

Four steps from order to lab report.

01 Kit arrives Ships the next working day, postage paid to your door.
02 Collect urine Urine sample at home with the material provided.
03 Send it in Post it in the postage-paid envelope.
04 Get your lab report 7–21 days after the sample arrives.

Instructions

The essentials first:

Collect the urine sample in the container provided, as described in the instructions.
Close the sample tube tightly and label it.
Send it in the postage-paid envelope, as soon as possible after collection.

Please read the instructions carefully. Correct preparation matters: it is what allows your sample – stool, urine, saliva or blood – to be evaluated cleanly and meaningfully.

Sending your sample back

So that your sample reaches the laboratory safely, please follow the rule for your country.

Family and partner diagnostics

Testing together shows connections that a single analysis does not reveal. We need three things for it.

Clear details per person For each person tested we need a name and date of birth, so the laboratory can match everything correctly.

An email address of their own Each person needs an individual email address for secure digital access. If that is not possible, we send the results as a PDF to a shared address.

Clear labelling Samples and forms must each be assigned to exactly the right person.

From three tests of the same analysis for the family you get 10 % off. Write to us and you will receive your own discount code.

Reimbursement by private insurance

For possible reimbursement by your private insurer, this is how it works with us:

01 A short online consultation with one of our therapists We go through your symptoms and put together a short, suitable case history.

02 A referral for the appropriate lab tests After the consultation you receive a referral you can submit to your private insurer.

Many private insurers cover the cost in full or in part – some not at all. That depends entirely on your policy. We support you through the process as best we can.
